Grail exhaust system suitable for Audi RS6 C7 Avant (4.0 TFSI V8-Biturbo) – valved exhaust system

The Audi RS6 C7 Avant (2013-2018) is one of the great classics of the Audi Sport era: a 4.0 TFSI twin-turbo V8 with 560 hp in the pre-facelift version and up to 605 hp in the facelift Performance Edition - commanding, powerful, in an estate body. The GRAIL valved exhaust system unlocks the full acoustic potential of that twin-turbo V8: deep, dark, with a clear eight-cylinder character. Made from L304 stainless steel, CNC-machined to close tolerances, with ECE type approval - no registration required on any EU vehicle with standard type approval.

Valve control via the Audi Drive Select driving modes

The valves are controlled by the factory Audi Drive Select valve control of your RS6. In Dynamic mode the valves open; in Comfort or Auto mode they stay closed.

Configurator - choose pre-facelift or facelift

The system comes in two versions, one for each model phase:

• Pre-facelift: the original launch version with 560 hp from the 4.0 TFSI twin-turbo V8
• Facelift: the revised version, including the 605 hp Performance Edition

The geometry of the system was slightly revised with the facelift - hence two separate versions.
